Parallel Circuits - Goodheart
... So far we have assumed that R1 equals R2. This is not always so. Often they are unequal, and there is not an equal division of currents flowing in the branches of the parallel circuit. In Figure 7-5, when the current reaches point X, it will still divide, but the greater amount of current will flow ...

By adding more tollbooths in a series so that they are all connected by a single pathway, the tollbooths effectively slow down the flow of cars because the cars would have to pass through every tollbooth on the path. This corresponds with our observation that adding more resistances to a ...
